Tires: Description and Operation
Tread Wear Indicators

Tread Wear Indicators Description 

The original equipment tires have tread wear indicators that show when you should replace the tires.

The location of these indicators are at 72 degree intervals around the outer diameter of the tire. The indicators appear as a 6 mm (0.25 inch) wide band
when the tire tread depth becomes 1.6 mm (2/32 inch).
